Here are some possible solutions:
1) Try a new bobbin, and if you wind your own, make sure it is wound very tightly
2) Take the bobbin case out and make sure there are no stray threads stuck down there, they can wreak havoc! To do this, unscrew your throat plate and lift the bobbin case out. Then use your lint brush that came with the machine, or another small soft brush and give it a thorough cleaning under there.
Hope these help!

There are a couple of reasons that can cause this.
a. Raise the pressure foot. As you load the top thread give small tugs to check for snags. They must be stopped.
b. Once the top threading is done on top lower the pressure foot. Now, give a tug on the thread. Is the tension really hard or just average? You may need to lower the tension to stop the jamming of the bobbin thread.
c. Clean the bobbin area. Check the bobbin tension and adjust as you need to.
d. Put a drop of oil on the race. (Thing the bobbin case sits on)
e. As the bobbin hook (sharp thing) is rotating does the bobbin case move back and forth a lot. You may need to adjust the bar that is next to the bobbin case so it can't rotate. Usually you will need to move it forward.
SEE INSTRUCTIONS HOW TO ADJUST THE BOBBIN. TENSION OF UPPER AND LOWER THREAD MUST BE RIGHT.

Change needle
Clean under needle plate where feed dogs are for lint
Clean bobbin area for lint or loose threads
Rethread machine top thread make sure to get every thread guide
& bobbin is threaded correctly & inserted in the bobbin case or shuttle correctly
Check tension 3 or 4 is usually good

after you try all this & it keeps jamming then it may need to be serviced

Debris and loose thread around the bobbin cage. All it takes is a tiny piece of thread in the right place.

Bobbin inserted backwards in the "bobbin holder". When installed correctly, There is some resistance when you pull on the thread, but the bobbin will spin without trying to pop out of the "bobbin holder".

check that the bobbin thread is pulled thru 'the tongue' of the bobbin case: that is what controls general tension of the lower thread. also make sure the upper thread is threaded thru the tension disk and the disk is 'grabbing it'.

* Change your bobbinThere could be a nick along the edge of your bobbin spool that’s catching your thread as yousew.

* When you start to sew a seam, grasp the upper and bobbin thread tails. Hold them backand out of the way as you sew your first couple of stitches. This will keep them from gettingcaught in your machine.

It sounds like you are not threading the machine properly. The best way is to make sure the presser foot is in the up position. This keeps the tension disc open and the thread slides into the tension easier. Also make sure you have the bobbin in and threaded correctly into the bobbin case.

Take the bobbin carriage out and clean it really good. Use the little brush that comes with your machine and brush everything. When m y machine jams up like that it usually means there is lint or thread caught in the bobbin carriage.

I'm fifi1076, and I'm having quiet a good bit of trouble with my sewing machine.

I'm new at this site so I don't know if I'm doing this correctly or not so please forgive me if I do something I'm not suppose to do!!!!

I copied this question from off of this site for I wanted to make certain that whoever answers my question will understand that all of the question doesn't pertain to my problem.

"when we have it threaded the top thread keeps getting jammed up in the
bottom bobbin. if i redo the bobbin as shown in manual then the bottom
thread will not loop so it will stitch"

This is the only part that pertains to my problem...... when I have it threaded the top thread keeps getting jammed up in the
bottom bobbin......and I can't get it to sew at all....it won't do nothing.....the motor will just sit there and grind.

If whoever can help me with this and can give me a solution I will be forever gratefull

Are you making sure that your pressure foot is up when you thread the upper thread? If it isn't then your thread is not seating correctly in the tension disks. It will then be loose and make a birds nest(mess) under what you are trying to sew. The other thing to check is which way you are putting the bobbin into the bobbin case, different machines do it different ways. Some want the thread to come out of the case in the same direction as the slot on the case and some want it to come off in the opposite direction.

Guest,
Probably when your son broke the needle he knocked it out of time. You will need to have a sewing machine technician to repair that.
